PROCESS OF CANNING FOOD.

SPECIFICATION forming part of Letters Patent No. 411,436, dated September 24, 1889.

' Application filed November l0, 1888. Serial No. 290,421. (Model.)

To all whom/t may concern:

Be it known that I, JOHN H. J. IIAINES, a citizen of the United States, and a jesident of Flushing, in the county of Queens and State of New York, have invented a certain new and useful Process of Canning Alimentary Substances, of which the following is a specification.

In the manufacture of canned goods it has been heretofore proposed to employ tinned iron or other material comprising, essentially, a base ot some inferior metal, having a coating or lining directly attached to it and cornposcd of tin or some other material which will not act injuriously upon the contents of the can. It has also been proposed to make packing cases or cans for various materials from wood, paper, or pasteboard, having an interior lining of thin metal secured in place therein, the joints for the interior lining being ordinarily formed by compressing the edges of the sheets or pieces making up such lining together.

The form of can last described is not adapted to the canningof alimentarysubstancessuch as fruits and vegetables which ordinarily require that the can itself should be highly heated, in order to drive olif moisture or air from the contents preliininarily to the sealin g of the can.

In the forms ot' can first mentioned the metal lining is firmly attached to the baser met-al; but the latter very often becomes exposed and spoils the contents of the package, and in the process of canning the lining of tin and the iron body are necessarily heated together. i

My invention relates to the improvement hereinafter described in putting up alimentary substances in cans having a thin metalfoil lining for the body of the can; and it consists, essentially, in making the thin metal foil lining and the can separately, placing the substance to be canned into the metal-foil lining or capsule of tin or other metal which will not act injuriously on the contents, sealing the same by fusing the edges of the foilsheets together, and then placing the metal lining and contents into the body of the can.

Figure l is a vertical section of a complete can manufactured according to the process forming my invention. Fig. 2 is a vertical section of an apparatus which may be employed in the process.

Referring to Fig. l, A indicates the metaltoil lining, which may be formed in one or several pieces, as desired, and which is closed at its head by a sheet of foil, (indicated at B.)

D indicates the body of the can, which may be made of paper, pasteboard, wood.` or any other desired material, and is provided with ascrew-cap or otherwise attach ed cover, (indicated at E.)

The body of the can or pasteboard or other suitable material may be formed in any desired way. The lining of metal, in which the substance to be preserved is immediately contained, is made separately, being constructed, either in two pieces or in one, as a capsule whose bottom and sides are integral with one another, and the contents of the package-as fruit or vegetables-are placed in such capsule, and the cover-plate of tin-foil is. united thereto by the device shown in Fig. 2, in which G indicates a ring, of any desired material, mounted ou suitable standards, and II a central plate or ring adapted to clasp the upturned edge of the covering-disk and the upper edge of the body of the capsule between itself an d the outer ring G. The edges of the cover and the body are left projecting slightly, so that by passing a heated soldering-iron over the exposed edges the cover and body may be united together and a good seal formed through the fusion together of the melted edges. After the fruit or other substance has thus been inclosed in the metalfoil lining, such lining, with its contents, may be heated, for the purpose of driving ofic any contained air or moisture, after the manner usually adopted in the case of tinned-iron cans or vessels. The latter operation having been completed and the package sealed, it may be readily introduced into the body or exterior wall of the can made of paper, cardboard, or other suitable material, the latter operation completing the process.

I do not limit myself to the use of tin-foil, but may use any other desired metal adapted to be sealed by the process described.. The

process of forming a joint between two surfaces of Inetalfoil through the Jfusion of eX- posed clamped edges I do not herein claim.

In order to protect the joint against rupt- IOO ure from the movement of the contents of the capsule or lining, I employ, as shown in Fig. l, a disk I, which is fitted tightly into the concavity in the head and compresses or holds the joint firmly against the inner wall of the exterior case.

I do not claim herein, broadly, a tin-foil package.

I do not claim in this application the method or process of putting up aliment-ary or other substances in paper or other cans having metal-foil linings, consisting in forining the complete metal-foil lining around the substance to be packed and then completing the body of the can or package, of ypaper or other material, with the complete sealed lining inclosed therein, as this forms the subject of another application for patent {iled by mc June 2l, 1889, Serial No. 315,100; but

The herein -described method of canning alimentary substances in paper or pasteboard cans having metal-foil linings, consisting 1n forming the lining, and the paper or pasteboard body separately, inclosing the material in the metal foil, sealing the saine by fusion of the metal-foil edges together,l subjecting the lining and contents to the proper heat, and, finally, applying the body of the can to the lining, as and for the purpose descr bed.

Signed at New York, in the county of New York and State of New York, this 5th day of November, A. D. 1888.

JOHN H. J. HAINES.
